I could do a Firestorm design with an electric flipper but anyway. I think the Storm 2 design is the best idea for starters. what kind of tyres should I use, the pneumatics or solid wheel ones?
Solids. Or pneumatics filled with foam (or something like that - if I remember correctly Stingers tyres were filled with rags).
There are a lot of good tyres to be found these days. Best are rubber ones. You could use those that you find on those 2-wheeled thingies for kids (forgot the name). Theyre solid AND have grip. Also the ones you find on shopping trolleys.
Or the Robochallenge blue wheels.
I just had a crazy idea. Why not use a wheel-barrow as the shell? It has a wedge on the front and it has aliminum shielding already. It could be cut down to the size of the chassis.

The middleweight doom did that. Unsure if it would be a little too heavy for a feather
Would I need 4 speedos for 4 motors or can I wire 2 motors on to one speedo? If I could then how could I wire one battery on to one speedo?
You can wire 2 motors onto one speedo however you must make sure that the speedo can take the current drawn by both motors without giving out the magic smoke.
You can wire a single battery to both speedos by wiring the speed controllers up in parallel with the battery. This allows you to have a larger single battery pack.
How do I make sure that the speedo can handle the current drawn by both motors?

Kevin, If I were you Id invest in some reasonably cheap yet high-current speed controllers such as the Electronize controllers (which can be found at http://www.technobots.co.ukwww.technobots.co.uk).
Having read from the start of this thread I beleive you are more familiar with the type of speed controller often used with cheap RC Cars which usually comes in the form of a POT (Potentiometer) directly connected to a servo for proportional current control. This method is very fragile for use with a combat robot and probably would not handle the current required unless you have a particulary large POT. I definately reccomend investing in a speed controller similar to the Electronize or just an on/off servo operated swich if you really cant afford anything much. An on/off switch would make the driving particularly hard but should handle the current much better than a POT if you choose the right switch.
Sorry if I bored you
